Answer:

50°

Step-by-step explanation:

I am assuming that the shape is a right triangle.

All interior angles of a triangle add up to 180°.

$x + 40 + 90 = 180\\\rule{150}{0.5}\\x + 130 = 180\\\\x + 130 - 130 = 180 - 130\\\\\boxed{x = 50}$

The missing angle should be 50°.

Hope this helps.

Answer:

$\boxed{50 }$

Step-by-step explanation:

<h2>What is a Triangle?</h2>

A triangle is the simplest polygon. It is a two-dimensional shape with three straight sides forming an interior, closed space. It has three interior angles.

1. Subtract the two known angles from 180°

2. Plug the two angles into the formula and use algebra:

$\boxed{a+b+c=180}$

3. Subtract

$\boxed{180-40 =140}$

$\boxed{140-90=50}$

$c=50$

Therefore, The Answer is 50

Find the measure of the missing angle. a 66°

yanalaym [24]

Answer:

24°

Step-by-step explanation:

the total angle, made up from both a and 66°, is a mini-square, as you can see. this represents a right angle of 90°

thus, a and 66° combine to make 90°

a + 66° = 90°

subtract 66 from both sides to get a

a = 24°
